Assembly without tools● Straightforward assembly, exchange

and maintenance with no need for tools of any kind

● Simple reversal of the air flow direc-tion by turning the fan module

● Individual positioning of the power connection

● Spring clamp terminals for electrical connection without tools

● Louvred grille latch for fast filter mat replacement without tools

Efficient technology● Air throughput from 20 to 700 m³/h

● New diagonal fan technology for greater pressure stability and constant air flows in use, even with a contaminated filter mat

● Minimum installation depth

● Flow-optimised air routing

● Extended service life of filter mats and thus longer maintenance intervals

Air routing● Intelligent symbiosis of radial and

axial fan technology

● Air flow spreads diagonally from the fan, promoting a more even air distri-bution in the enclosure

Hose-proof hoodFor fan-and-filter units/outlet filters. When the hose-proof hood is mounted above the fan-and-filter unit and outlet filter in conjunction with a fine filter mat, a protection category of IP 56 to EN 60 529 is achieved.

Material:Stainless steel, silicone

Protection category:In conjunction with the fan-and-filter units/outlet filters, NEMA 3R + 12 is met.
